Windows 7 actually works differently when it is installed on an SSD:

When a solid state drive is present, Windows 7 will disable disk defragmentation, Superfetch, ReadyBoost, as well as boot and application launch prefetching.

I'm not sure if all this will be done automatically if you clone to an SSD instead of a fresh Windows install...
